ABSTRACT:
The substrate of a magnetic recording medium is laser textured employing a dual fiber-optic laser delivery system which enables separate control of nucleation and crystallization. An embodiment of the invention includes laser texturing glass, ceramic and glass-ceramic substrates without microcracking to form a texture comprising uniform protrusions.
